Earthdata forum transition

The Ocean Color Forum (including our subforum for Field Data - SeaBASS) has transitioned to the burgeoning Earthdata Forum (https://forum.earthdata.nasa.gov/). We encourage you to ask questions there and we look forward to interacting with you.

The new forum is organized using tags. Pick the "SeaBASS" tag to search for existing SeaBASS posts, or when you create a new post. There are a variety of search options; if you use the "Search By Tags" feature then SeaBASS is under the dropdown "Major Project". Other relevant tags include "Ocean" for Discipline and "OB DAAC" as the DAAC.

You can bookmark your favorite searches using your browser if you want a shortcut. Also, later this year a feature will be added allowing you to follow specific tags and receive email notifications whenever there is a new post.


New website look

The SeaBASS website has received a new look to go along with several background updates and small accessibility changes.


filename extension change (.sb)

The filename extension ".sb" is now officially used to identify the SeaBASS file format. Read more. Data submitters, please use ".sb" when creating future file names (instead of .csv, .txt, etc.) Data users should note that a large percentage of historical files have had their names updated to the new standard. Other than the metadata "/data_file_name" being updated, the contents and format are otherwise unchanged.
